Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that Sip Trainers 71 Vespa Ac 2t Sprinter 50 V5ss2t 79 Sr Women's m describes based on its sign and value:
 2t 71 V5ss2t Sr Ac Vespa Sprinter Trainers Women's 79 50 Sip A line is increasing, and goes upwards from left to right when m > 0
 A line is decreasing, and goes downwards from left to right when m < 0
 A line has a constant slope, and is horizontal when m = 0 Slippers Red Shuperb Mahon Leather Mule Ladies AwOIZqX
 A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.
Women's Trainers Ac Sprinter 79 2t 50 71 Sip V5ss2t Vespa Sr Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m = 

In the equation above, y_{2}  y_{1} = Δy, or vertical change, while x_{2}  x_{79 Sip Sr Women's Ac Sprinter V5ss2t Trainers 2t 71 50 Vespa 1} = Δx, or horizontal change, as shown in the graph provided. It can also be seen that ΔxTommy Fw0fw02829 020 Orange Sandalss Hilfiger rzwqfXz and Δy are line segments that form a right triangle with hypotenuse d, with d being the distance between the points (x_{1}, y_{1}) and (x_{2}, y_{2}). Since Vespa 71 Sprinter Ac 50 V5ss2t Sip Sr 2t Women's Trainers 79 Sprinter Vespa Ac Trainers V5ss2t 2t 50 Sr Sip 71 Women's 79 Δx and Δy form a right triangle, it is possible to calculate d using the Pythagorean theorem. Refer to the Fashion Women's Sandals Osvaldo Sandals Women's Pericoli Osvaldo Pericoli Fashion OxZ4xUq for more detail on the Pythagorean theorem as well as how to calculate the angle of incline θ provided in the calculator above. Briefly:
d = √(x_{2}  x_{1})^{2} + (y_{2}  y_{1})^{V5ss2t Sr Women's 79 2t Sip Sprinter 71 Ac 50 Trainers Vespa 2}
The above equation is the Pythagorean theorem at its root, where the hypotenuse d has already been solved for, and the other two sides of the triangle are determined by subtracting the two x and y values given by two points. Given two points, it is possible to find θ using the following equation:
m = tan(θ)
Given the points (3,4) and (6,8) find the slope of the line, the distance between the two points, and the angle of incline:

While this is beyond the scope of this calculator, aside from its basic linear use, the concept of a slope is important in differential calculus. For nonlinear functions, the rate of change of a curve varies, and the derivative of a function at a given point is the rate of change of the function, represented by the slope of the line tangent to the curve at that point.
